[0002] Mechanical and electrical installation includes the installation of various equipment, communications, fire protection, HVAC, water supply and drainage, electrical appliances and automatic control systems in civil, public and industrial projects, as well as subsequent installation, commissioning, trial operation and final acceptance. The installation process also includes steps such as foundation layout, equipment placement, accuracy inspection and adjustment, equipment fixing, disassembly, cleaning and assembly, and lubrication and equipment refueling. Each step is very important and directly related to the quality of the installation project and the operating effect of the mechanical and electrical equipment.

[0003] Mechanical and electrical installation is mainly about the installation of equipment and lines. Equipment usually has a set installation position. In order to ensure the stability and safety of the equipment after installation, it is usually necessary to set up a channel steel bracket to position and install the equipment. The channel steel bracket needs to be manufactured and formed according to the specifications and shapes of the equipment, including L-shaped and T-shaped connections of the channel steel. Both of these connections usually require welding to ensure the stability of the channel steel connection and to support the installation of the equipment.

[0004] At present, during the processing of channel steel brackets, a large amount of smoke and dust is generated during cutting and welding, which seriously pollutes the on-site environment. The welding operation in a limited space is risky. A large amount of smoke and dust is generated during welding, and the on-site space is limited. The smoke and dust are not discharged in time, which can easily cause suffocation incidents. With the development of society, the environmental protection requirements for on-site construction are high, and the traditional bracket processing method can no longer meet the processing needs. Summary of the invention

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a channel steel assembled connection structure, characterized in that: the connection structure is a first connection structure and a second connection structure in which the side ends of the connected channel steels are sequentially assembled with each other, and after assembly, the connected channel steels are relatively limited to form a first connection structure.

[0007] Preferably, the connected channel steels are L-shaped, and the first connection structure and the second connection structure are inverted trapezoidal protrusions and trapezoidal grooves alternately arranged at the oblique side ends of each channel steel and matching each other.

[0008] Preferably, the connected channel steels are L-shaped, and the first connecting structure and the second connecting structure are protrusions and grooves that are alternately arranged and cooperate with each other at the oblique side ends of each channel steel, and arc-shaped grooves that together constitute connecting holes are opened on the adjacent protrusion sides of the connected channel steels.

[0009] Preferably, the connected channel steels are T-connected, the first connection structure is an inverted trapezoidal protrusion opened on the side of one of the channel steels, and the second connection structure is a trapezoidal groove provided at the end of the connected channel steels.

[0010] Preferably, the connected channel steels are T-shaped, the first connecting structure is a protrusion opened on the side of one of the channel steels, the second connecting structure is a groove set at the end of the connected channel steels, and arc-shaped grooves that together constitute a connecting hole are opened on the adjacent sides of the protrusion and the groove.

[0011] The beneficial effects of the present application are as follows: after the first connecting structure and the second connecting structure that cooperate with each other are arranged at the side ends of the connected channel steels, when assembling the channel steels, the mechanical assembly connection can be realized through the first connecting structure and the second connecting structure, and the limited fastening of the connected channel steels can be realized after the connection, so as to solve the problems of difficult operation, long construction period and serious pollution caused by the current welding, and effectively improve the assembly efficiency of the channel steel in the electromechanical installation. The connection structure reduces the amount of welding of the channel steel connection, improves the efficiency of the channel steel bracket production, and achieves the purpose of reducing costs and increasing efficiency. The prefabricated factory prefabrication is adopted to reduce the on-site welding work. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached Figures 1 to 12 A channel steel assembly connection structure is shown, in which the first connection structure and the second connection structure are sequentially arranged at the side ends of the connected channel steels 1 to assemble each other, and after assembly, the connected channel steels 1 are relatively limited to form a first connection structure. After the first connection structure and the second connection structure are arranged to match each other at the side ends of the connected channel steels 1, when assembling the channel steels 1, a mechanical assembly connection can be achieved through the first connection structure and the second connection structure, and the limited fastening of the connected channel steels 1 can be achieved after connection, so as to solve the problems of difficult operation, long construction period and serious pollution caused by the current need for welding, and effectively improve the assembly efficiency of channel steels in electromechanical installation.

[0027] Example 1

[0028] like Figure 1-3 As shown, in this embodiment, the connected channel steels 1 are L-shaped, and the first connection structure and the second connection structure are inverted trapezoidal protrusions a1 and trapezoidal grooves a2 alternately arranged and matched with each other at the oblique side ends of each channel steel 1. Before the channel steels are assembled and connected, the ends of each channel steel 1 are beveled in advance. Figure 1The structure shown, during installation, the L-shaped connection of the channel steel 1 is achieved by the nesting cooperation of the inverted trapezoidal protrusion a1 and the trapezoidal groove a2 of the connected channel steel. In order to avoid the problem that the connected channel steel 1 is displaced up and down under the influence of external force and the nested inverted trapezoidal protrusion a1 and the trapezoidal groove a2 are disengaged, it is preferred to selectively perform spot welding operations on the joints of the connected channel steels 1 after the nested assembly to improve the tightness after connection and avoid up and down disengagement after force.

[0029] In order to ensure that the surfaces of the connected channel steels are flush, Figure 1 As shown, during the pre-cutting process, matching steps 11 are cut on the side walls of the connected channel steels 1 to facilitate surface positioning of the matched connected channel steels and ensure surface flatness after later assembly.

[0030] And it is also preferred to set up the connection hole c of the following embodiment 2, and by passing the connection screw through the connection hole c, the quick fastening connection operation of the connected channel steels 1 can be achieved.

[0031] Example 2

[0032] like Figure 4-6 As shown, the connected channel steels 1 are L-shaped connected as in Example 1, wherein the first connection structure and the second connection structure are protrusions b1 and grooves b2 alternately arranged and matched with each other at the oblique side ends of each channel steel 1, and the assembly method is the same as that of Example 1, and the protrusions b1 and grooves b2 of the connected channel steels 1 are nested and matched with each other, thus completing the assembly connection of the channel steels. The assembly structure adopted in Example 2 is faster than that in Example 1 in the later assembly and nesting, but its limiting effect is lower than that in Example 1. Therefore, in order to improve the limiting and connection tightness of Example 2, as shown in FIG. Figure 4-5 As shown, arc grooves c1 are provided on the sides of adjacent protrusions b1 of the connected channel steels 1, which together form the connection hole c. That is, the side wall of the protrusion b1 of each channel steel 1 is pre-opened with an arc groove c1. After the channel steels are nested and connected, the arc grooves c1 of adjacent protrusions b1 are opposite to each other, thus forming the connection hole c ( Figure 5 As shown), a screw and a nut are then inserted into the connection hole c to achieve the fastening connection operation of the connected channel steels.

[0033] Example 3

[0034] like Figure 7-9As shown, the connected channel steels 1 of this embodiment are T-connected, the first connection structure is an inverted trapezoidal protrusion a1 opened on the side of one of the channel steels 1, and the second connection structure is a trapezoidal groove a2 set at the end of the connected channel steel 1. During assembly, the inverted trapezoidal protrusion a1 and the trapezoidal groove a2 are nested in the same manner as in Embodiment 1-2 to achieve a T-connected structure of the connected channel steels. It is also preferred that the connection is strengthened by spot welding after connection, or a connection hole c is set as in Embodiment 2, and the connection is fastened by bolts.

[0035] Example 4

[0036] like Figure 10-12 As shown, the connected channel steels 1 of this embodiment are T-connected, the first connection structure is a protrusion b1 opened on the side of one of the channel steels 1, the second connection structure is a groove b2 set at the end of the connected channel steel 1, and arc-shaped grooves c1 that together constitute a connection hole c are opened on the adjacent sides of the protrusion b1 and the groove b2. Compared with embodiment 3, this embodiment has a faster nesting assembly efficiency. After assembly, in order to improve its stability, by selecting a connecting screw and a nut to be inserted into the connection hole c, the channel steel can be fastened and connected to form a T-shaped structure.

[0037] The principle of the present application is: a first connection structure (such as an inverted trapezoidal protrusion a1 and a protrusion b1) and a second connection structure (such as a trapezoidal groove a2 and a groove b2) are pre-cut and set at the joint of the connected channel steels 1. During assembly, the L-type connection and T-type connection of the channel steel 1 can be achieved by nesting the first connection structure and the second connection structure, and preferably, a tight assembly connection can be achieved by spot welding or by inserting a connecting screw in a pre-opened connection hole c, thereby solving the problems of difficult operation, long construction period and serious pollution caused by the current need for welding, and effectively improving the assembly efficiency of channel steels in electromechanical installation.

[0038] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
